Comparative study of the therapeutic effect of Doxorubicin and Resveratrol combination on 2D and 3D (spheroids) cell culture models
Research Overview
Drug combinations for pancreatic cancer are usually assessed in 2D culture. This study compared the therapeutic effect and synergistic potential of a doxorubicin-resveratrol combination in 2D monolayers versus 3D spheroids of PANC-1 pancreatic cancer cells — the first such direct comparison for this pairing.
Molar ratios from 5:1 to 1:5 were tested. Viability was most affected by combinations containing higher resveratrol content (1:2 to 1:5 ratios), a result attributed to resveratrol’s own activity — and the 2D-versus-3D comparison shows how much the culture format shapes apparent combination efficacy.
Key Discoveries
- First direct 2D-versus-3D comparison of doxorubicin-resveratrol combinations in pancreatic cancer
- Molar ratios from 5:1 to 1:5 tested against PANC-1 monolayers and spheroids
- Resveratrol-rich ratios (1:2 to 1:5) most reduced viability
